You click on one of the properties that come up on the search, and you will be taken to that home's description page.

If the home is covered by Street View, you can find it below the property's description.

There are also other tabs on this gadget which allow you to see the property on all other features of Google Maps except Terrain.
Trulia's integration of Street View is a great example of Google's success in indexing the world so far. And although the images may not be perfect, they are very accurate, which is why so many are turning to Google now for information.
